The voltage coil 7 is connected to the battery 2 and is energized. Therefore, the plunger 5 is attracted upward in the drawing, and the movable contacts 4c come into contact with the fixed contacts 4a and 4b of the main contact 4. At this time, the other end 11a of the lever 11 moves to the left in the drawing, so that the one end 11b moves to the right and the pinion 10 moves to the ring gear 13. Therefore, the armature 9 is energized and rotated by the closing of the main contact 4, and the pinion 10 meshes with the ring gear 13 to transmit the rotational force of the armature 9 to the ring gear 13 to start the engine. In this case, the lever spring 12 is compressed when the pinion 10 and the ring gear 13 are in contact with each other, that is, when the end faces are in contact with each other, and the pinion 10 is moved to the ring gear 13
It is arranged so that it can be easily pressed and engaged with.

題があった。The conventional switch control device for the starting motor is configured as described above, and has the following problems. That is, in the past, two kinds of exciting coils, that is, a current coil and a voltage coil, were used to maintain a closed state by the plunger by first flowing a large current to move the plunger and then flowing a smaller current. There is. Therefore, 2
Since the type of exciting coil is provided, the entire apparatus becomes large and heavy, and it is impossible to reduce the size and weight of the apparatus and simplify the structure. Next, as shown by the solid line in FIG. 5, the plunger suction force increases substantially in the form of a quadratic curve from the start of the start switch 3 at point A to the suction completion P 1 to P 2 . That is, since the exciting coil is suddenly applied with the power supply voltage of the battery 2, the plunger 5 moves with a strong force, so that the pinion 10 violently collides with the ring gear 13 via the lever engaged with the plunger 5, and the pinion The 10 and the ring gear 13 could be damaged. In addition, since the magnetomotive force is expressed by the current x the number of coil turns, when the coil temperature is high (when the coil resistance is large), the applied voltage for flowing the current necessary for attraction is naturally high. Since it was designed with consideration given to it, the suction force was unnecessarily high at low temperatures. Further, due to the abrupt movement of the plunger 5, the lever spring 12 is compressed to move the fulcrum 11 rather than moving the pinion 1.
As a result, c will move, and as a result, the main contact circuit will be closed faster, and when the pinion 10 and ring gear 13 mesh,
Since the number of rotations of 10 has been increased, there is a problem such as poor meshing.

る電流制御手段とを備えたものである。A switch control device for a starter motor according to the present invention generates an electromagnetic force when a current flows, and the electromagnetic force causes the plunger to move to close and hold the main contact. The current flowing through the exciting coil increases with time until it is closed, and
After the main contact is closed, the current control means is provided to reduce the current to maintain the closed contact.

Therefore, the switch starts attracting when the current necessary for attracting flows, and therefore the pinio moves. Is smoothly performed, and the pinion is smoothly engaged with the ring gear. Further, after the main contact is closed, the holding current is generated, and the heat generation of the exciting coil is suppressed to the minimum.

Is a starter motor, which includes a switch unit 101a and a motor unit 101b. The motor unit 101b has the same configuration as the motor unit 1b of the conventional device. 67 is an exciting coil, one end of which is connected to the battery 2 via the starting switch 3 and the other end of which is connected to the drain terminal of the power MOSFET 51. Reference numeral 61 is a control circuit, which is a start signal 31 from the start switch 3 and the main contact 4
The main contact closing signal 41 from is input to control the gate of the MOSFET 51. The source of the MOSFET 51 is grounded. Further, 71 is a diode that absorbs the back electromotive force of the exciting coil 67. Since other respective configurations are similar to those of the conventional device, corresponding parts are denoted by the same reference numerals and the description thereof will be omitted.

イル67の電流は主接点閉路から減少してゆく。Next, the operation of the switch control device having the above configuration will be described. When the start switch 3 is closed, the start signal 31 is input to the control circuit 61, the control circuit 61 turns on the MOSFET 51, and the exciting coil 67
Is energized. 3 (a) and 3 (b) show MOSFET 51, respectively.
7 shows the on / off state of and the change in the current of the exciting coil 67. Here, S is the control start time, the MOSFET 51 is turned on / off as shown in the drawing, and the duty increases with the passage of time (t 1 / T <t 2 / T <t 3 / T <...), Therefore, the current of the exciting coil 67 also gradually increases corresponding to this increase, and the magnetomotive force thereof gradually increases (in FIG. 3 (b), the broken line indicates the average current). The main contact 4 closes at point m,
After that, the holding current is operated (t 6 / T), and the control ends when the starting switch 3 is opened at the point e. Therefore, the current of the exciting coil 67 decreases from the main contact closed circuit.

First, the process proceeds from the starting step 201 to step 202, and if the starting switch 3 is turned on, the process proceeds to step 203 to perform the above-described gradual increase control of the exciting coil 67 current. Next, at step 204, if the main contact 4 is closed, proceed to step 205 to set the holding current, then step 2
If the start switch 3 is turned off in 06 (normally, the engine is started), the control ends (step 207). If the start switch 3 is not turned on in step 202, control proceeds to step 207, and if the main contact 4 is turned off in step 204 and the start switch 3 is turned on in step 206, This is repeated without shifting to the next step.

であるため、スイッチの発熱も減少する。FIG. 5 is a diagram showing the relationship between the plunger position and the suction force. The broken lines F 1 to F 4 show the above embodiment, point A is the rest position (normal plunger position without operating the start switch 3), and point B is The main contact 4 closed circuit position, 0 point is the absorption completion time point. In this way, the plunger 5 starts moving from the minimum force required for suction (F 1 point), reaches the F 2 point as the current gradually increases, becomes the holding current (F 3 point), and when the suction is completed, the F 4 point Reach Therefore, the switch unit 101a starts the suction at the time when the current necessary for the suction flows, so that the movement of the pinion 10 is performed smoothly as compared with the conventional device, and therefore the rise of the motor due to the compression of the lever spring 12 does not change and the pinion 10 and A smooth mesh with the ring gear 13 can be achieved. Further, after the main contact 4 is closed, there is only the holding current, so the heat generation of the switch is also reduced.

Further, the switch control device may be integrally formed with the switch, and in this case, the function can be added by replacing the switch. Further, the signal line for the main contact closing signal 4 can be omitted if the main contact closing signal 4 is not used and the holding current is controlled when a predetermined time has elapsed after the start switch 3 is turned on.

損傷が防止される。また、噛合時のピニオンの回転上昇
が低くなり、噛合が円滑に行える効果を奏する。As described above, according to the present invention, an electromagnetic force is generated by the flow of an electric current, and the electromagnetic force causes the plunger to move to close and close the main contact, and the main coil closes and holds the main contact. Current control means for increasing the current passing through the exciting coil with time until the main coil is closed, and reducing it to a current that can maintain the closed circuit of the contact after the main contact is closed. The two types of coils become one type of exciting coil, that is, the two types of coils are made up of one type of coil, so the size and weight are reduced. Furthermore, the current of the exciting coil is gradually increased up to the main contact closed circuit. Since the number of contacts is reduced after the contacts are closed, the plunger can be moved smoothly and the pinion and the ring gear can be prevented from being damaged. Further, the rotational increase of the pinion at the time of meshing is reduced, and there is an effect that meshing can be performed smoothly.
